Why the homeless shelter was closed due to a methane gas leak?

I asked once before concerning soaked uncooked kidney beans. seems the uncooked beans did have a negative effect. the cook at the soup kitchen that served the raw beans to the homeless men is to blame for the major gas leak that followed. Untold misery and greif. the men lived in a building that had no venilators and there sleeping rooms were windowless and and crowded beyond limits. The uncooked beans brewed inside the men to the point of one major release. methane levels rose and they closed the shelter temporarly to air the place out.Any clue on how to stop soup kitchen cooks from serving dangerous food would help ? the moral of the story is watch what you eat because you never know if any one sat on it. That must be were flat sandwiches come from. So again I ask what I can I do to stop the soup kitchen cooks from serving dangerous food its a tough call because after all the food is free, what they are forgeting is it does not have to taste good but it does need to be safe.
